Why do massive stars form bow shocks? Bulk ISM motion as the main driver of bow shock formation and geometry

J. van den Eijnden, L. Kaper

Bow shocks are one the most commonly observed impact sites of massive star feedback. Their existence is often taken as evidence of the supersonic motion or even runaway nature of t…

OB runaway stars originating in the Vel OB1 association

N. Azatyan, L. Kaper, A. Samsonyan +4

OB runaway stars are massive stars moving through interstellar space at high velocities (up to 200 km/s), produced by dynamical ejections in young massive clusters or supernova exp…

The origin of the most recently ejected OB runaway star from the R136 cluster

Simon Portegies Zwart, Michel Stoop, Lex Kaper +3

The solar-mass (\MSun) star-cluster R136 (NGC~2070) in the Tarantula Nebula in the Large Magellanic Cloud is the host of at least 55 massive stars ($M \apgt 10$\,\MS…

ALMA detections of circumstellar disks in the giant Hii region M17. Probing the intermediate- to high-mass pre-main-sequence population

J. Poorta, M. Hogerheijde, A. de Koter +8

Our current understanding is that intermediate- to high-mass stars form in a way similar to low-mass stars, that is, through disk accretion. However, the physical conditions that p…

Two waves of massive stars running away from the young cluster R136

Mitchel Stoop, Alex de Koter, Lex Kaper +10

Massive stars are predominantly born in stellar associations or clusters. Their radiation fields, stellar winds, and supernovae strongly impact their local environment. In the firs…

Properties of intermediate- to high-mass stars in the young cluster M17 -- Characterizing the (pre-)zero-age main sequence

Frank Backs, S. A. Brands, M. C. Ramírez-Tannus +5

The outcome of the formation of massive stars is an important anchor point in their evolution. It provides insight into the physics of the assembly process, and sets the conditions…
